Spotting Image, Audio and Video Manipulation

Practise identifying whether digital images, audio clips and videos have been altered. Learn to tell the difference between ordinary edits for clarity and changes made to mislead viewers. Use simple checks to decide on a selection of media examples.

    1 - Start ~4 mins

    Illustration for StartYou already know that digital media can be cropped, filtered, trimmed and layered. Today the question flips.

    Today’s question

    When you meet a finished image, clip or soundtrack online, can you tell what was done to it?

    Your callWhat it means
    As takenNo good reason to think the capture was changed.
    Fair editingChanged for clarity, length, framing, quality or privacy, without inventing a false story.
    Altered to misleadChanged so people believe something untrue.

    You will make these calls from practical tells — clues you can see or hear — rather than guesswork.

    2 - Examine and Discuss ~6 mins

    Illustration for Examine and discussNot every change is a trick. A sports photographer crops a wide shot so the goal fills the frame. A news desk brightens a dull flood photo so the waterline is clear. Those are ordinary edits.

    Manipulation becomes a problem when the change is hidden and the viewer is led to believe something untrue: a sentence cut from a speech so the meaning flips, or a clip sped up so a calm corridor looks chaotic.

    Today's three verdicts:

    • As taken: nothing meaningful has been changed from the original capture.
    • Fair editing: changes were made for clarity, length, framing, quality or privacy, and they do not invent a false story.
    • Altered to mislead: the change is designed (or likely) to make the audience believe something untrue.

    You will build a short tell checklist on the board as you work the first live item.

    3 - Hands-on: Manipulation Forensics ~14 mins

    Work through each item in the interactive activity as a class. For every piece, look at what is on the board (caption, source, and the photo, audio or clip description), weigh what you notice, and commit to one verdict: as taken, fair editing, or altered to mislead. Then reveal the reasoning and check it against your call.

    Argue out loud. The skill is naming what changed and whether that change invents a false story, not racing to a score.

    As taken, fair edit, or altered?

    4 - Your Turn ~10 mins

    On your own or in pairs, judge these two items. Look at each picture before you read anything else, then write three short lines for it.

    Item 1Item 2
    A small Irish harbour on a clear morning with two fishing boats on calm waterA market stall with crates of apples, baskets on the ground and a stack of jam jars
    Source: named local photographer
    Caption: “Quiet morning at the pier.”
    Source: shop’s own post
    Caption: “New batch on the shelf today.”
    For each item, write

    Verdict — as taken, fair editing, or altered to mislead.
    What may have changed?
    The one tell that decided it.

    Where to look

    Compare things that should be different from each other: two of anything that look exactly alike are worth a second look. Check that light and shadow agree across the whole picture, and that reflections match what is above them.

    Before you finish, check:

    • a verdict on both items
    • one clear tell named for each
    • at least one item where you can say why it is as taken or fair editing rather than a lie

    5 - Make Sense ~3 mins

    Pull the three verdicts back together.

    Your callWhat it means
    As takenNo good reason to think the capture was changed.
    Fair editingChanged for clarity, length, framing, quality or privacy, without inventing a false story.
    Altered to misleadChanged so people believe something untrue.
    Key point

    The skill is not a perfect detector. It is slowing down, naming the tell, and asking what a viewer would wrongly conclude if they trusted the piece at full speed.
